OrientDB : Can't find symbol OGraphDatabase - orientdb

Question

I searched some examples on the Internet and many of them use the OGraphDatabase. However, when these code file was compiled, a exception that says cant find the symbol of "OGraphDatabase" was throwed.
Blow is the source code:
public class TestTreeGraph {
static OGraphDatabase db;
//static int i=0;
//static ODocument currentNode;
public static void main(String[] args) throws FileNotFoundException{
String dbpath="/Users/wuguirongsg/orientdb/orientdbgraph";
File dbfile = new File(dbpath);
if(!dbfile.exists()){
//dbfile.mkdirs();
db = new OGraphDatabase("local:"+dbpath).create();
db = new OGraphDatabase("local:"+dbpath).open("admin", "admin");
}else{
db = new OGraphDatabase("local:"+dbpath).open("admin", "admin");
}
ODocument rootNode = db.createVertex().field("id", 0);
int i=1;
createNode(rootNode,i);
db.setRoot("treegraph", rootNode);
}
private static void createNode(ODocument node,int i){
if(i>=20){
System.out.println("i>=10================== back ");
return ;
}
ODocument leftNode = db.createVertex().field("id", i + "_vertex_left");
System.out.println("create "+i + "_vertex_left ");
ODocument rightNode = db.createVertex().field("id", i + "_vertex_right");
System.out.println("create "+i + "_vertex_right ");
ODocument edgeleft = db.createEdge( node, leftNode);
ODocument edgeright = db.createEdge( node, rightNode);
edgeleft.save();
edgeright.save();
//currentNode = leftNode;
System.out.println("go left");
createNode(leftNode,i+1);
System.out.println("go right");
createNode(rightNode,i+1);
System.out.println("==================");
}
}

OGraphDatabase has been deprecated ages ago. You can use OrientGraph.
Example
String dbpath="C:/test";
OrientGraphFactory factory = new OrientGraphFactory("plocal:"+dbpath);
// if the database doesn't exist it is created and opened
// if the database exists, it is opened
OrientGraph db = factory.getTx();
// inserting a vertex
Vertex rootNode=db.addVertex("class:V");
rootNode.setProperty("myId","0");
db.shutdown();
